Specification of Letters Patent.

Patented Nov. 21, 1 9O 5.

Application filed November 19, 1904. Serial No. 233.457.

To aZZ whom it may concern.-

Be it known that I, BURT O. KELLY, acitizen of the United States, residing at Petroleum, in the county ofWells, State of Indiana, have invented certain new and useful Improvements in Belt-Stretchers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to belt-stretchers such as are employed in drawing the ends of a belt together and .holding them while they are being laced or otherwise fastened together, the object of the invention being to provide a cheap and simple construction with which the ends of the belt may be drawn together with the expenditure of a minimum of energy.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation showing a stretcher embodying the present invention. Fig. 2 is a top plan view of the stretcher. Fig. 3 is a detail perspective view of the guidebar. Fig. 4 is a detail View of the pull-bar. Fig. 5 is a detail View of a belt-clamp with the members thereof separated.

Referring now to the drawings, there is shown a belt-stretcher comprising a guidebar, including the side members and 11, connected at one end by the web portion 12 and connected also intermediate of their ends at intervals by the vertically-spaced pairs of transverse braces 13, between which is slidably received one end of a pull-bar 14, which projects from the guide-bar at the opposite end from the web 12, and its projecting end is provided with a pivoted hook 15. The pull-bar is adapted to telescope into the inclosure of the guide-bar. Between the free ends of the sides 10 and 11 of the guide-bar is pivoted a plate 16, which projects above and below the guide-bar and forms a head of a lever, and attached to one end of its plate is a handle 17. Pivoted to the plate 16 above and below the pivot of the plate are pawls 18 and 19, respectively, which are adapted to engage successively in the perforations 22 of the pull-bar 14. The pawls are held normally and yieldably in position to engage their fingers with the bar 14, through the medium ofhelical springs 23 and 24, respectively, which are connected to the pawls and to the hooks 25, respectively, on the plate 16. By compressing the rear ends of the pawls their fingers may be discharged from the bar 14, as will be understood. With this arrangement it will be understood that by rocking the plate 16 upon its pivot the pawls will be shifted in opposite directions along the pull-bar, and it will be noted that the fingers of the pawls converge in the direction of the web 12 of the guide-bar, so that they engage the perforations of the pull-bar when moving in the direction of said web portion and are disengaged from the perforations when moving 1n the opposlte direction. Thus the pull-bar is shifted in the direction of the Web 12.

At the outer ends of the guide-bar and pull-bar are hooks 15 and 31, each of which is engaged with the bail of a belt-clamp. The belt-clamp comprises jaws 33 and 34, through one end of which is passed a clamping-bolt 35. The opposite ends of the jaws have slots 36 and 37, respectively, and a second clampbolt 38 is hinged to the jaw 33, so that it may be swung into and out of the slots 36 and 37. When the bolt is engaged in the slots 36 and 37, its nut 39, together with the nut 40 of the bolt 35, may be adjusted to move the jaws toward each other to grip the end of a belt between them. The grip-faces of the jaws have cavities 41 therein to permit the belt to sink thereinto when gripped, and thus prevent slipping of the belt from between the jaws.

It will be understood that in practice modifications of'the specific construction shown may be made and any suitable materials and proportions may be used for the various parts Without departing from the spirit offulcrum and disposed to engage the perforatively to the free ends of the guide-bar and tions of the pull-bar in the direction of the pull-bar. I Web portion of the guide-bar, means for hold- In testimony whereof I afiix my signature in ing the pawls yieldably in engagement with presence of two witnesses. 5 the perforations, said pawls being movable BURT O.
